IMPROVE CHAIR.

To ALL WHoM 1T MAY coNcERN:

Be it known that'I, HARRISON COLE, of Cincinnati, in the county ofHamilton, and State of Ohio, have invented certain new and usefulImprovements in Chairs; and I do hereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings, making part ofthis specification, in which Figure 1 is a perspective view of myimprovedchair.

Figure 2 is a rear view of the double tripod.

The nature of my invention consists, irst,in the form of'the doublemetallic tripod, by which the chair is supported, for the purpose' ofgiving elasticity to the seat.

In the-drawings, A represents what I have called a double tripod,consisting of two truncated tripods .connected at the point oftruncation, and strengthened by the brace A", vvhich tripod forms thelegs or standard of the chair.A B is the chair-bottom, secured to theupper portion of the tripod by screws at C C C. -The feet of thestandard are fastened to the door by screws passing through the lugs C;CC.

This tripod is cast in a single piece because of its greater economy,and so that all the parts are more rmly connected together for mutualsupport, and by the curvature of the legs, especially of thefront legA', a degree of elasticity is obtained, which takes oi` the strain fromthe screws which secure'the feet, and prevents themirom beingwrenchedfrom the door when the'sitter leans backward, as is frequentlythe case with chairs whose standards are rigid or nou-elastic. Y

Having thus described my inventionfwhat I desire to secure by LettersPatent, i's- 'The three-legged chair-standardA, in combination with thebrace A and the lugs C C C and C C C, for attaching it to the door andchair-bottom, substantially as shown. I

Y HARRISON COLE.
